Abstract: The invention relates to a spectrophotometer, especially a spectrophotometer that can carry out simultaneous analysis at different points on the same sample (4), with a high spatial resolution and without requiring a mechanical system for physical scanning along the sample. This is obtained by the provision of means for processing the light received by the photodetectors (5), said processing means having a correlation wherein each of the photodetectors (5) corresponds to a spatial point on the sample (4).In the case of dark field applications, the present invention ensures the standardization of the data using the same measure.

Abstract: Systems and methods for extracting topographic information from inspected objects to identify defects in the inspected objects. A part to be inspected is illuminated with at least two different colors emitted from an illuminator providing a gradient of light consisting of the at least two different colors. A single color image of the illuminated part to be inspected is acquired, providing a color-coded topographic mapping of the part to be inspected due, at least in part, to the gradient of light. Topographic monochrome views of the part to be inspected may be generated from the single color image. Each view of the topographic monochrome views may enhance a different type of feature or defect present in the part to be inspected which can be analyzed and detected.

Abstract: A device for measuring optical spectra at high speed and with high resolution using tunable optical laser comb sources. In one embodiment there is provided a first tunable comb laser source and a second tunable comb laser source whereby the wavelength of each comb laser source is chosen such that the combination of the two sources provides a continuous spectral coverage over a band in an optical spectrum under a selected wavelength tuning condition. By overlapping the two comb sources in the manner described the deadzone issue is overcome in the most spectrally efficient way possible.

Abstract: In a Raman microscope, a depth measurement processor performs depth measurement by changing a focal position of laser light along a depth direction of a sample which is an irradiation direction of the laser light with respect to the sample, and meanwhile, acquiring a Raman spectrum of the sample at a plurality of points in the depth direction. The display processor causes Raman spectra obtained at the plurality of points by the depth measurement to be displayed. The display processor can display a surface image of the sample on the stage and a depth image representing a plurality of points in the depth direction and causes, in a case where at least one point of the plurality of points in the depth image is selected, the Raman spectrum corresponding to the at least one point to be displayed.
